"The Esplora sketch was modified to poll the joystick (4 directions) and the right button cluster. When they are activated, an appropriate ASCII character is sent via serial to the XBee which sends it to the Uno which controls the head via a Motorshield."

"We’re exploring a whimsical project to collect breathalyzer data from various locations for use in visualizing local trends in intoxication. This weekend I completed the first step by prototyping simple hardware that reacts to various amounts of booze on the breath."

"This article describes how to implement a very low bandwidth one way communication channel between an Arduino and an Android device using nothing more than about a meter of magnet wire, a resistor and diode. Links to a software sketch for the Arduino and the Android source code is included."

"The Challenge: To design and build a sequencing control system for 64 solenoids that control a mixture of UV tonic and air into a manifold of pipes to be pumped around a structure. This was for a team participating in the Luxcity Project."

"Arduino shield for controlling something without touching the controller. Great for Touchless Gesture User Interface experiments, artistic expression and game controllers. Does not use special parts, just a bunch of CMOS chips connected to an ATmega328 in the form of an Arduino Uno board."

"Jonathan Ward from the MIT Center for Bits and Atoms has designed a snap-together, desktop-sized CNC milling machine. The MTM Snap is made from 1/2-inch high-density polyethylene (HDPE) – itself milled on a ShopBot – and can be assembled for about $700. This three-axis CNC machine can mill circuit boards, wax molds, and harder materials in a 5x3x1.75″ working area. "

"A PID controller is like a kind of fancy thermostat, but can be used to control pretty much any kind of process, not just heating and cooling. This project was inspired by the osPID and its design is greatly indebted to that pioneering device."

"The mood that the ‘Magic Crystal Mood Ball’ gives to the user is based on measuring his temperature and changing the color of the RGB LED to the its respective color. As in a mood ring, I set different colors for different temperatures. The temperatures coincides with mood state that the person is in."

"This January my daughter decided that she wanted to join in her brother’s cub pack’s Pinewood derby with a replica of Doctor Who’s TARDIS on wheels. Her design was pretty straightforward – balsa wood trim, poster paint, paper cutouts for the windows and sign, and her construction was quickly nearing completion…."

"I have decided to do a small hardware project to get my feet wet, a project that I will fully document and discuss here with the hope to encourage and motivate others to do the same: Building an Arduino Robot."
